Because the from address can be forged, probably.

Not really a problem in the age of DKIM, _if_ you want to solve it.

Yeah, it may be a combination of “not everybody uses DKIM” and “too few users actually use their address book”.

No, that kind of software optimizes a very important problem. It’s quite cumbersome to set up all components of a mail server by yourself. At some point you start hosting a domain for a friend. Then then friend wants to create some mailboxes, forwardings and so on by themselves. So you just give them SSH and tell them to edit the postfix config? Having a web interface that does it all and doesn’t break things is very…

This problem is solvable without a web interface: https://manpages.ubuntu.com/manpages/bionic/man5/dot-qmail.5...

How many people understand that man page, and how many people understand a web interface? I think it’s a clear winner.

First thought: oh, huh, a self-hosted CVE generator. In seriousness, installing Roundcube on my own server circa 2006 was the cause of the first and only time I’ve had a server hacked. It’s probably improved since then or it wouldn’t still be around, but it put me off ever hosting my own email. The risks only get worse the further away you get from personal/hobby use.

I've used https://mailu.io . It works well, but your biggest problem is going to be getting over the spam filter hurdles of the email giants of the world. Even if everything is properly configured (including dkim / spf / whatever else they've added) your messages will get plopped in the spam folder.

>getting over the spam filter hurdles of the email giants of the world

You mean global monopolies, for which there is no legislation for. Ergo the US Govt is holding the rest of the world hostage via its tech companies.

Dovecot, Roundcube, ClamAV, Rspamd are all battle-tested and reasonable choices, but the choice of Haraka, a Node.js-based SMTP server, feels dubious. Why not exim or something similarly solid and well-understood?

I generally recommend replacing Roundcube with SnappyMail ( https://snappymail.eu ) -- not having to deal with a database by not maintaining much state is a win. I was expecting to see Postfix instead of Haraka. I wouldn't have been very surprised at exim.

Does it sync contacts via CardDAV?

I never understood what use Webmail is, if you can’t access your contacts. Every email client I use, needs access to my contacts.

I feel like this solution is optimizing the wrong problem. The bulk of work with managing a mail server (these days) isn't software setup and admin. On the receiving side, it's all the work dealing with abuse and attacks. On the sending side -- and this is the tough one -- it's getting sites to accept your email. When I finally gave up managing my own mail server (about two years ago), I found that about every six mo…

I hosted my own mail for some time and got into trouble with the school of my kids because they did not receive my reply to their mail.

I self hosted because I wanted to prefer not to be part of the huge o365/Gmail/iCloud monocultures.

Last year I moved my mail to an old fashioned shared webhosting account at Hetzner. Very happy with it!

from can be forged, but spf is there so only valid servers can send mail (or at least non valid can be filtered).

SPF can break with automatic email forwarding (though DKIM usually shouldn’t).

I _love_ playing around with (and sometimes actually) self-hosting stuff. But email is something that I will HAPPILY pay someone like FastMail or ProtonMail ~$5/mo to handle and avoid myself the hassle. It just works. I can add whatever subdomains/addresses/sending profiles/etc., and I don't ever have to think about data backups, blacklists, spam reputation, or any of the dozen other issues I've heard about since I became aware of how email hosting works in ~2006.

Kudos to those of you in this thread who live the dream, though (really).

Not really a problem in the age of DKIM, _if_ you want to solve it.

Even with DKIM, all you need is the recipient of one email from one user on one domain (I have hundreds of domains) of your mail server to file a spam report, and WHAM you are blacklisted. So yes, it is a problem even with DKIM. If you have a solution, I would LOVE to hear about it.

If you’re blacklisted, the mail usually doesn’t even reach the spam folder.

I really have zero complaints or reason to move off Mailcow https://mailcow.email/

Does not run on anything other than x64. Otherwise it's perfect.

If you want to host email on your raspberry at home, your main issue is usually that your IP will be in a known „dial-up“ IP range, that is blocked by all major email providers. And most home internet providers block port 25 too. And you need a fixed IP, it’s a nightmare if your mail server‘s ip ever changes.
